I know that in GDScript I can export a variable as a PackedScene with the syntax:

export (PackedScene) var Bullet

My question is: how can I do the same thing in GDNative C++ with the register_property() instruction, without obtaining a ‘Nil’ (NULL) value by the emitter of the signal in the function “shoot()”?

I know that a modular method of working says “calling down, signal up”, so I don’t want to call “get_parent()” in the function “shoot()”, just emit a signal with the reference to the Bullet as a PackedScene.
